G(-8) means the x in the g(x) function is -8.

So plug in -8 in the x of the g(x) function.

g(-8) = -18(-8) + 2
g(-8)= 144+2
g(-8)= 146

Given: — Xw Is an altitude M Prove: x=12

blsea [12.9K]

Answer:

See explanation

Step-by-step explanation:

Given: XW is an altitude

m∠XWY=8x-6

Prove: x=2

Solution:

Statement Reason

1. XW is an altitude Given

2. m∠XWY = 90° Definition of altitude

3. m∠XWY = 8x - 6 Given

4. 8x - 6 = 90 Substitution property

5. 8x - 6 + 6 = 90 + 6 Addition property of equality

8x = 90

6. x = 12 Division property of equality

Can i have some help i need to find the surface area

makkiz [27]

Answer:

644ft^2

Step-by-step explanation:

Area of triangle=1/2bh

Area of square=l*l

so we have;

4 triangles with a base of 14ft and height of 16ft and 1 square with l=14ft

AreaTriangle=1/2(14ft)(16ft)=112ft*4=448ft^2

AreaSquare=14ft*14ft=196ft^2

Area Total=448ft+196ft=644ft^2

Expand the polynomial and simplify: (4xy− 1 8 y^2)^2

Vinvika [58]

Answer: $4y^{2}(2x-9y)^{2}$

Step-by-step explanation:

We have the following polynomial:

$(4xy-18y^{2})^{2}$

This is a polynomial of the form $(a-b)^{2}=a^{2}-2ab+b^{2}$ . Following this rule to expand it, we have:

$(4xy)^{2}-2(4xy)(18y^{2})+(18y^{2})^{2}$

$16x^{2}y^{2}-144xy^{3}+324y^{4}$

Applying common factor $4y^{2}$ :

$4y^{2}(4x^{2}-36xy+81y^{2})$

Note the polynomial inside the parenthesis is a perfect square trinomial, which can be factored to $(2x-9y)^{2}$ . Hence, the final simplification is:

$4y^{2}(2x-9y)^{2}$

Please help me asap!

diamong [38]

V= x*(10-2x)(8-2x)

for greatest volume, differentiate v w.r.t x and equate to 0,

dv/dx= (10-2x)(8-2x) + x(-2)(8-2x)+ x(10-2x)(-2)=0

you get x from solving the quadratic equation. volume will be max at that x
